Abstract:
To investigate the distribution of ticks and to detect the new bunyavirus in ticks and infection rate in animals in Shanghai,outdoor free ticks were captured by flag method and ticks on animals were collected by animal capture.SFTSV in ticks were detected by real-time RT-PCR.Total antibodies against SFTSV in host animal sera were tested by double antigen sandwich method.Results showed that during 2012-2014,free ticks were captured in Chenshan Park and Jinshan Island,which were all Haemaphysalis longicornis.Ten of seventeen districts found ticks on animals which were dominantly Rhipicephalus sanguineus.No nucleic acid of SFTSV was detected in 143 ticks.Main host animal for ticks was dog,sheep was in the second.Sera in 198 dogs from 6 urban districts,120 swine from Pudong and Fenxian districts and 36 sheep from Chongming District were all SFTSV antibody negative.Ticks were not found with SFTSV in Shanghai during 2012-2014.No SFTSV infection was found in host animals.Therefore,there is no evidence that Shanghai is the natural foci of SFTSV.Further surveillance and investigations should be carried out in the future.
